REMARKS
 During acceleration/deceleration, the running frequency within the set
area is valid.
 If the setting ranges of individual groups (1A and 1B, 2A and 2B, 3A
and 3B) overlap, Er1 (write disable error) will occur.
 Up to three areas may be set, with the
 The value set to 1A, 2A or 3A is a jump
Example 1
To fix the frequency to 30Hz in the range of 30Hz to
35Hz, set 35Hz in Pr.34 and 30Hz in Pr.33.
Example 2
To jump the frequency to 35Hz in the range of 30Hz to
35Hz, set 35Hz in Pr.33 and 30Hz in Pr.34.
